Default Re: tearing with vdpau on multi-monitor setup

It's now half way through 2012, I'm using a GTX 460, I have a Dell U2711 as my primary monitor and a 42-inch Sony TV as my secondary monitor, and this issue is unresolved (as far as I can tell).

When I boot into Windows 7, everything works fine, dual-monitor is flawless, zero tearing when playing YouTube or movies on either monitor.

When I boot into Ubuntu 12.04 (64-bit) running either the 290.10, 295.59 or 302.07 binary drivers, I get a slow tearing effect on the Sony TV (TwinView mode). This tear slowly moves from top to bottom. Very annoying, forces me to use Windows 7.

I would pay for a solution to this, as I love using Ubuntu 12.04 and really want to return to using it at home. It's getting close to the time I usually upgrade my graphics card. After buying nVidia my entire life (and recommending nVidia to my friends), I'm now seriously considering buying an AMD Radeon next time, just to see if it makes any difference.

I've read in various Ubuntu forums that the problem with TwinView is the card cannot sync to two monitors in TwinView unless each monitor has the exact refresh rates. I've tried so many suggested fixes, nothing works.
